1. Question 5.3.2 · May/June 2025 · Paper 1 · National (DBE) · 3 marks
Water is drawn from a water source $12, 5$ m below the ground by an electric pump. The water is lifted vertically upwards at a constant speed, as shown in the simplified diagram below.

The pump lifts the water upwards at a rate of $2, 5$ kg·s $^{- 1}$ . Ignore ALL frictional and capillarity effects.
5.3 The pump lifts $200$ kg of water from the source to the ground at a constant speed. Calculate the:

3. Question 1.4 · November 2022 · Paper 1 · Provincial · 2 marks
Four options are provided as possible answers to the following questions. Each question has only ONE correct answer.
1.4 In the diagram below, a pendulum bob of mass $m$ is released from point A and swings past points B, C and D. Ignore all effects of air resistance.

In which of the following positions will the value of the gravitational potential energy of the pendulum bob be the smallest?(2)

2. B B
3. C C
4. D D

1. ✓
  Choose the correct option $E_{P} = m g h$ . The mass and $g$ are the same at every point, so $E_{P}$ is smallest where the height is smallest. C is the lowest point of the swing (the bob hangs straight down).
  
  Answer: C
